Abstract

Neuralgic amyotrophy involving the lower trunk of the brachial plexus, particularly the ulnar nerve, is exceedingly rare. Here, we report a 41-year-old female who presented with acute right shoulder pain and paresis of the right hand. An electrodiagnostic study showed patterns compatible with acute axonopathy of the right ulnar nerve. However, other electrophysiologic, laboratory, and imaging studies failed to identify a clear cause of the neuropathy. After receiving five weeks of systemic steroid and five months of rehabilitation program, pain and grip strength gradually improved. This is a rare case of neuralgic amyotrophy with isolated ulnar nerve involvement confirmed by an extensive diagnostic workup.
